gnome-keyring

I just tried a pkg_rolling-replace -ruv, with CVS-head, and ran into:
RR> Selecting gnome-keyring (security/gnome-keyring) as next package to replace
RR> Replacing gnome-keyring-2.28.2
===> Cleaning for gnome-keyring-2.30.1nb1

==========================================================================
The following variables will affect the build process of this package,
gnome-keyring-2.30.1nb1. Their current value is shown below:
* PAM_DEFAULT = openpam
Based on these variables, the following variables have been set:
* PAMBASE (defined, but empty)
* PAM_TYPE = openpam
You may want to abort the process now with CTRL-C and change their value
before continuing. Be sure to run `/usr/bin/make clean' after
the changes.

This strikes me as a little odd, as at the top "Replacing gnome-keyring-2.28.2"
and the conflict is with the very same gnome-keyring-2.28.2.
Am I missing something?
